To all whom it may concern:

Be it known that 1, HEINRICH AUGUST Fnmnnrorr FRANKE, asubject of the German Emperor, and resident. of Charlottenburg, have invented'a certain new and useful Improvement in Devices for Feeding Cigarette-Papers, of which the following 1s a specification.

The manufacture from blades of marze of cigarette papers which are not used in rolled form like known papers, but are used when already cut and stacked in piles has hitherto been impossible in the production of machine made cigarettes, because the gripping and lateral feeding of the individual papers from the pile has been practically impossible mechanically as in lateral movement ota paper, in consequence of the projecting veins, the papers directly above the one abstracted have been carried forward with it;

The present invention relates to mechanical means for abstracting the individual papers from the pile without also feeding those adjacent the same and for delivering the-paper's for the next operation.

According to the invention a movable suction member is guided below the lowest or over the uppermost paper of the pile, whereupon 'the'pile of papers is lowered or raised against the mouthpiece of the suc- I tionmember so that the lowest (or the uppermost) paper is removed exactly verv tically of the pile and clings closely to the mouthpiece. Thereupon the pile isv again raised or lowered and the suction member moved laterally. The paper is then delivered to the apparatus for performing the y next operation by forcing air under pressure through the suction member. With this mode of transport of individual cigarette papers by means of a suction device it is thus possible to use in the mechanical production of cigarette papers. stacked in a pile and composed of blades of maize.

Apparatus for carrying out the present method is shown diagrammatically by way of example in the accompanying drawing.

Referring to the drawing, 1 is the holder in which the pile of leaves 2 is fed in from above while for supporting the pile 2, short projections 3 are provided on the four corners of the lower open end of the holder 1. Beneath the holder v1 is arranged the movable member 4 serving for transporting the holder leaves 2. This member comprises a tube having a mouth piece 5 of oval cross section which tube is pivoted about a, horizontal branch The branch 6 is connected to a pump 7, the piston 8 of which is moved by .a bell crank lever system 9 through the intermediary-of an eccentric rod 10 from a continuously'rotated driving shaft 11. On movement of the piston 8 in the direction of the arrow 12 air is drawn through the pipe 4, while on movement of the piston in the opposite direction air is blownthrough the pipe 4. By means of a grooved-cam 13 keyed on the driving shaft 11, the tube 4, through the intermediarypf the connecting rod 14:, which engages with a roller 15 in the groove of the cam 13, after removal of a est paper from the pile may be eiiected.

reliably by means of the suction mouthpiece 5, the pile, at the moment of withdrawal, must lie close againstt-he mouthpiece 5. To this end, the mouth-piece may also be connected with the branch 6 bye in a vertical direction, or, as shown, the pile holder itself may receive'a vertical movesbaft, the eccentricity corresponding with the required amount of movement; the rod engaging a fork 22 mounted on the holder 1. In order to prevent adhesion of the pile 2 in the holder 1 to the mouth-piece 5 which might take place when the eccentric mechanism for the holder is-fht one of its dead points a stop 23 provided with a buffer suitable hose connection so as to be movable cushion is arranged on the upper end of the Y 1, which stop on the dbscent of the holder comes in contact with the edge of the guide 24.

The rod 21 for actuating the holder 1 is keyed to the cam disk 13 at such an angle that the holder 1 is lowered against the suction pipe when the latter is stationary,.while the holder 1 is raised shortly before the suc tlon pipe 4 is moved toward the right.

As already indicated, instead of moving the holder 1 relatively to the suction pipe 4 and vibrating the latter I may impart any other combined movement to the pipe 4 so that the pipe 4 shall firstmove vertically upward against the pile and then after revmo val of a paper move laterally relative to the pile.

Having described my invention what I claim an desire to secure by Letters Patent of the United States is 1. In a paper feeding'machine the combination of a guide carrying rollers, a holder for a pile of papers mounted to move vertically on said rollersja laterally movable suction member arranged below the pile of pa- .persin; the holder, an air compressor connected with the suction member,and means for moving-,t-he holder vertically, the suenation of a box-shaped guide carrying rollers on the inside thereof, a holder for a pile of papers mounted to move vertically on I said rollers, a pivoted suction member arran ed below' the pile of papers in the holger, an air compressor. connected with the suction lnember, a shaft, a cam fixed to the shaft, a connection between the cam and the suctionmember whereby the latter is actuated, means for moving the holder by the shaft, and means for operating the air con1- pressor from the shaft, substantially as described.

3. In a paper feeding machine thecombination of a box-shaped guide carrying rollers on the inside thereof, a holder for a pile of papers mounted to move vertically on said rollers, an air compressor, a suction member pivotally connected to the air compressor and arranged below the pile of papers in the holder, a shaft, a cam fixed to the shaft, a connection between the cam and the suction member foractuating the latter, means for moving the holder from the shaft, an eccentricon the shaft, an eccentric rod operated by the eccentric, and a bell-crank forming a connection between the eccentric rod and the piston of the air compressor, substantially as described.

4.' In a paper feeding machine the combi-. nation of a box-shaped guide carrying rollers, a holder for a pile of papers mounted within the guide on said rollers adapted to move vertically, a stop carried\ by the holder for limiting its downward movement, an air compressor having an outlet, asuctionlmember pivotally connected to the outlet and arranged below the pile of papers in the holder, a shaft, a cam fixed to the shaft, a connection between the 'cam and the suction member for actuating the latter, an arm projecting from the holder, means connecting the arm and the shaft for moving the holder, an eccentric on the shaft, an eccentric rod operated bythe eccentric, and a bell crank pivotally connected to the eccentric rod and to the piston of the air compressor, substantially as described.

In testimony whereof I have signed my name to-this specification in the presence of two subscribing witnesses.
